UNITED STATES PATENT OFFICE 2 Claims.

This inventic .4 relates to supporting means for articles which are to be painted such as window sashes, screens, blinds, or the like.

An object of this invention is to provide an exceedingly simple detachable supporting means which may be readily mounted on a step ladder, the device being so constructedthat it can be mounted on either the side of the ladder or on the step of the ladder and when so mounted will hold or support articles with the upper ends of the articles leaning against theupper portion of the stepladder.

A further object of this invention is to provide in a device of this kind, means whereby the article to be supported will be prevented from slipping off of the support while at the same time, the device will not cover a considerable portion of the article and thereby prevent painting or other work being performed on the article.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a fragmentary vertical section of a stepladder of conventional construction having a device constructed according to the preferred embodiment of this invention mounted thereon,

the device being shown in side, elevation and a a window sash being mounted on the device, the window sash being shown in fragmentary vertical section.

Figure 2 is a horizontal section through the front portion of a stepladder and showing the supporting member in top plan, the supporting member engaging the side of the ladder.

Figure 3 is a perspective view of the device.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the views, the numeral Ill designates generally a stepladder of conventional construction which is provided with rungs or step members ll secured'to side members l2 and which are held in upright position by means of a swingable leg structure l3 shown here in fragmentary side elevation. This stepladder structure is of conventional construction and is shown here only as one means with which the hereinafter described invention may be used.

In order to support a sash, screen, blind or other article to be painted, repaired or otherwise serviced, I have provided a supporting member, generally designated as M. This supporting -member It comprises an elongated bar l5 preferably of straight form which is provided at its inner end with a substantially U-shaped clamping member l6 engaging about the step or rung II. The outer or free end of the bar I5 is provided with a laterally extending lug ll against 5 which the bottom of the sash or other-article designated S is adapted to engage. Preferably, there are at least two of these supporting members I mounted on the step or rung ll one adjacent each side of the stepladder. 10

Where the step II is so constructed that it is not possi le or convenient to have the U-shaped clamping member l6 mounted thereon, the clamping member I6 can be engaged with the side member l2 of the step ladder with the bar l5 l5 disposed on the inner side of the side member l2 and engaging the top surface of the rung or step member I I. When in this position, the sash S is held against outward sliding movement by one of the opposed lugs l8 disposed on the outer 20 end of the bar IS. The lugs I1 and [8 form a substantially T-shaped outer end for the bar I! and provide a means whereby the supporting member It may be easily and conveniently mounted on ladders of various types. 25

In the use of this device, where the stepladder has a step or rung H which does not have a rib or brace on the bottom thereof to prevent the engagement of the clamping member Ii therewith, the device is mounted between the sides I! 30 after the manner shown in Figure 1. Preferably, there are at least two of these supporting members mounted on the step ll, one adjacent each end thereof. Where it is not possible to slide the clamping member l6 over the step I I as shown 35 in Figure 1, due to braces or other means below the step II, the supporting member H can be mounted as shown in Figure 2, and in view of the opposed lugs l8 on the outer end of the bar 15, the device can be turned in any desired manner 40 preferably with the bar l5 on the inside of th side bar I! of the ladder.

Through the use of the device herein disclosed, it is possible to support articles such as sashes, screens, blinds or the like, on a stepladder so 45 that these devices can be painted, repaired or the like, and the articles can be supported at a convenient height.

What is claimed is:-

1. A means for supporting sashes or like 50 articles on a stepladder, comprising an elongated bar, a T-shaped outer end portion integral with the bar and disposed at right angles to the length of the bar and adapted to engage the lower edge of an article to hold the article from sliding oil 55 2 K i :a,o1s,s7s Y lugs integral with an end ot each bar, and a -U-shaped clamping member integral with the other end of each bar and adapted to ensue the stepladder for holding the bar in substantially ROY A. Davis.

61' the bar, and a olamping means carried by the other end of the bar for detachably mounting the 4 bar on the stepladder.

2. A meansior supportinz sashes or the like I on a stepladder, comprising a pair of elongated bars, laterally extendinl riaht anzularly related horizontal position.
